Australopithecus
afarensis is the species made famous by Lucy, a 3.18millionyearold
partial skeleton found at Hadar, Ethiopia. You see more reduced canines
and slightly thickened enamel, but afarensis still features a
protruding, chimplike jaw, and its brain is only slightly larger than
a chimpanzees. It has slightly longer arms and shorter legs than
a human does, but its proportions are very much like those of a human.
It has relatively curved fingers and toes.
